OIL COOKING-STOVE;

Specification of Letters Patent; Patented J 119 21: 1921 Application filed November 9, 1920. 7 Serial No. 422,938.

To aZZ whom it may concern:

Be it known that we, JAMns SHANNON and TVILLTAM MonnIsoN SIMrsoN, subjects of the King of Great Britain and Ireland, residing at. 37 Marquess road, Canonbury, in the administrative county of London, England, engineer, and 15 Godwin road, Hastings, in the county of Sussex, England, engineer, respectively, have invented certain new and useful Improvements in Oil Cooking- Stoves, of which the following is a specification.

This invention relates to cooking stoves or ranges in which oil burners of the Bunsen or atmospheric type are used, of the type having a plurality of heating burners which are supplied with the mixture of vapor and air hereinafter called the gas from a common genc'rator'coacting with one of the burners, and has for its object primarily to provide a convenient mode of sub-division of the source of heat to a number of units so that they may be used either separately or collectively, and to provide improved means of regulating the supply of gas to said units and generally to improve thistype of stove.

Vi e attain this end by providing a chamber under theburner co-acting with the vaporizer, by leading the supply pipe for the supplementary burners out of said charn ber, by the provision of means for distributing part of the gas generated by the burner co-acting with the vaporizer to the other burner or burners, by the provision oi means for bringing any of the supplementary burners into or out of action, and by the provision of means for regulating the supply of gas to the burner co-acting with the vaporizer without interfering with the supply of the other burners.

In the accompanying drawings which illustrate this invention Figure 1 is a view in front elevation of a stove constructed according to the present invention,

Fig. Q-is a view in plan thereof, V Fig. 3 is a view in transverse section through the main burner showing a convenient form of control, A V

Fig. 41- is a view in plan thereof,

Fig. 5 is a broken view in section on line mFig. hand Fig.6 is aview in planpartly in section-of the vaporizer.

Throughout the views similar parts are marked with like letters of reference.

The main burner comprises a fuel nozzle (4 an a r induction tube 6 hereinafter called the mixing tube, a chamber 0 into which" said tube leads, aburner rose or head 61 and a vaporizer c said vaporizer being connected to an oil container or reservoir f fitted with an air pump g'and the usual fittings. In order to steady the inflow of oil and the generation of vapor a wick k may be inserted in one or both of the connecting tubes 6 of the vaporizer. This wick may be formed either by winding a strand of asbestos twine on, a length of wire, as shown in one of said tubes in Fig. 6 or it may consist of a plain coil of wire as shown in the other of said tubes in the same figure- The fuel jet or nozzle a which is carried by a block a is fitted with the usual screw down valve for closing said jet or nozzle and a needle a carried by said valve for cleaning said jet or nozzle. j

Suitable means such as atrough Z to hold methylated spirit is provided for the initial heating of the, vaporizer and a similar trough m may. be provided to heat up the block a carrying the fuel jet or nozzle. These troughs may be provided with wick formed as before described or by winding asbestos twine transversely on a thin metal strip.

From, the chamber 0 a tube a extends horizontally at right angles to the mixing tube plementary burners independent; of the other or others and independently of the mam burner. I 7

To enable the mam burner to be regulated. without infli'iencing the supplementary burners any suitable regulating dev ce may be employed. A suitable one consistg of a tube 25 adapted to slide the tube I) said tube being provided with'means such as the handle i for operating it. The tubes projects into the chamber '0 and lies across the orifice of the conveyingtube a which is suitably shaped to engage wlth lt', and its inner. end engages wlt'h a cone-shaped pro ectlon o Too mounted on the wall of the chamberf In the tube; is a slot 25 which is of such a shape andsize that in all positions which said tube may occupy it is in communication with the conveying tube at, and thus at all times keeps the communication between the tube 11 and the generator open. The amount of gas passing to the main burner is regulated by opening and closing the inner end of the tube t by varying its position in relation to the projection o. A small permanent opening between the .tube' t and the chamber a such as the small hole i in said tube is provided so as to-keep the main burner in action at all times for the purpose of keeping the vaporizer hot. I j

The burners are mounted in a suitable and appropriate frame to for carrying cooking utensils or ovens or the like. 7

The gas may also be utilized for lighting purposes in conjunction with incandescent burners such a combination being shownby way of examplein Fig. 1 of the accompanying'drawing for the purpose of lighting the stove. candescent burner y is connected with the conveying pipe n by means of a pipe such as 2/- r What we claim 1s:-

1. An oil'cooking stove comprising a mainburner, a plurality of supplementary burn-f ers, an oil reservoir, means, for creating pressure in said reservoir, a vaporizer connected to saidreservoir, a chamber located below and in communication with said main burner, an adjustablefuel nozzle connected to said vaporizer, an induction or mixing tube co-actingwith said fuel nozzle and in communication with said chamber, a supply pipe for the supplementary burners leading outof said chamber, means forcontrolling the supply of gas to each of said burners in- .dependently of the others and means independent of the fuel nozzle for varyingvthe amount of gas passing to the main burner head independently ot the amount ,of gas passing to. the supply ,pipe of the supple mentaryburners. V V p 2. An Oll cookingstove comprisinga main burner, a plurality of supplementary burn-- able chamber located below the mainrburner,

a fuel nozzle in communication with said vaporizer, an induction'or mixing tube co-.

with the induction ormixingtube, means for; controlling the supply of gas from said supply pipe to each of said supplemental burn- In the arrangement shown the iners, and of valve means for putting the induction or mixing tube into communication with saidchamber.

s 3. In anoil cooking stove the combination of an oil reservoir means for creating pressure in said reservoir, a main burner head, a chamber under and in communication with said head, a vaporizer located above said head, and in communication with the oil reservoir, a fuel jet or nozzle in communication with said vaporizer, an adjustable needle valve controlling the orifice of said nozzle, an induction or mixing tube co-acting with said nozzle and leading into said chamber a plurality of supplementary burner heads, a conveyingtube connecting said chamber with said supplementary burners, cocks or valves for regulating the gas passing to said sup- 'plementary'burners, and means for regulat ing the relative amount of gas passingto the main and to the supplementary burners comprising a tube mounted to slide in the induction or mixing tube the inner end of which projects into the chamber beneath the main -b11l1161,-l coned plug mounted in said chamber and co-acting with the open endof said sliding tube to form a valve, and a slot or opening in said sliding tube cor-acting with i 4'. In an Oll cooking stove the combination ot'a main burner head, a chamber under and V .111 communication with sald head, an 011 ms -ervoir', means for creating pressure in said reservoir, a vaporizer located above said head and in communication with the oil reservoir, a fuel nozzle in communication with said vaporizer, an adjustable needle valve controlling the orifice of said nozzle, an induction or mixing tube co-acting'with said nozzle and leading into said chamber, a plurality of supplementary burner heads, a conveying tube connecting said chamber with' saidsupplementary. burners, cocks or valves for regulating the gas passing to said supplementary burners, a tube mounted to slide in. the induction or mixing tube the inner endof which projects into the chamber be- :neath the main burner, a coned plugmounted insaid chamber and co-acting with the open end oftsaid sliding tube to form a valve, a slot or opening in said sliding tube co-act- -thesupplementary burners to keep said con- :veying tube always open to the induction or mixing tube and, a bypass port in said ing with the orifice of the conveying tube of j sliding tube for keeping the chamber beneath the main burner constantly "Induction or'm xing tube.
